IMPROVEMENT IN WIRE-BARBING MACHINES.

Specification forming part of Letters Patent No. 209,544, dated November5, 1878; application filed f July 24, 1878.

To all whom it may concern:

Be it known that I, FRANK BILLINGs, of Cleveland, in the county ofCuyahoga and State of Ohio, have invented certain new and usefulImprovements in Machines for Making Barb Fence-Wire, which improvementsare fully set forth in the following specification and accompanyingdrawings, in which- Figure l is a perspective view. Fig. 2 is alongitudinal section. .Fig. 3 is an end View. Fig. 4 is a top or planview. Fig. 5 is a detached view of the core of the barb-twistingspindle. Fig. 6 is a detached View of the spindle or hollow shaft,showing the beveled end; Fig. 7, detached views of twisting-dies. Fig. 8is a detached view of a bushing which is contained in the end of thecore. A

The object of this improvement is to furnish a device to be attached tothe hollow shaft of my wire-barbing machine, for which a patent wasgranted the 18th day of June, 1878, as an improvement thereon, for thepurposev of making a variety of barbed fence-wire.

In the said machine there is contained a hollow shaft, B, carrying arotating cutting and twisting head, H, in which is contained a die, e,having a central aperture, through which the main wire or strand passesin the operations of the machine. The said die has two grooves, intowhich the barb-wires are fed, which are so located in relation to thesaid central opening that the barb-wires will lie one on each side ofthe main strand. The object of this construction of the die is to wrapor coil the barbs around the outside of the main strand.

The object of the improvement is to so construct the dies that the saidbarb-wires may be both fed between the two main wires, or that one ofthe barb-wires will lbe fed between the two main wires and the otheroutside, producing different results.

This is accomplished as follows: The aperture through the die forfeeding one barb-wire between the two main wires and one outside is madein oval form, with one end of the oval at the center of the die, so asto have the two main wires spread apart sufficiently to allow thebarb-wire to pass between them, the grooves in the face of the die beingarranged to lead the barb-wires one in between and the other outsideofthe two main wires.

To accomplish the other the central opening in the die is also made ovalin form, but longer in its major axis, and is across the center, whilethe grooves in the face are close together. In

this case the two main wires are spread farther apart and the barb-wiresare both fed between the two main wires.

In the first instance the coilin g of the barb- Wires by the rotatinghead produces this result-that is, one of the barbs embraces in its coilone only of the main wires, while the other barb in its coil embracesboth of the main wires and the other barb. lThis barbed wire is thesubject of my patent of June 25, 1878.

In the second instance the result differs from the first in this, thatthe two barbs, being both passed between the main wires when coiled, arelinked together between the main wires, and each barb in its coilembraces one of the main wires.

In the accomplishment of these results it has been necessary to providea guide through the aforesaid hollow shaft B for directing the mainwires through the die at the proper places. The said guide consists of acore, a, fitted within the shell of the hollow shaft, and has anindependent -movement imparted to it back and forth Within the shell bymeans of an inoline, c, on the end of said shell, bearing'against asimilar incline on a cross-head, a', on the end of the core a, the saidcross-head playing on two rods, b b, extending outward from the post B.Springs placed on the rods b b, between their heads andthe cross-head,serve to force the core inward when released by the incline. gitudinalbores, one for each of the two main wires, and in the end of the corenext to the head H is put a steel bushing, d, having two holes, throughwhich the main wires pass.

These holes are located so as -to hold'the said main wires in thecentral aperture of the die, in accordance with the barb-grooves in theface of the die, while the barbs are being fed therein.

The aforesaid outward movement is given to the core a for the purpose ofproviding Through said core are made two lonthe head H in wrapping onthe barbs.

forward the core a. is

space between its end and the die for the main wires to turn in duringthe revolution of Without this space the main wires would be twisted andkinked. When the head H. revolves back again, after the barbs have beenput on, thev the core a recedes by the force of the springs; then thefeeding forward of the main wires, and also of the barb-wires, againtakes place while the said core is in near the die. It is then that thecore serves as a guide and holder of the main wires. The incline on theend of the shell is so arranged in its relation with the core a. as toimmediately force the said core outward when the head begins itsrevolution for putting on the barbs.

The operation of this core attachment is as follows: When the main wireis to be fed forward the hollow shaft is at rest, with the head H inposition ready to perform its revolution for cutting off the barbs.Before this revolu- .tion takes place, however, the main wire must bemoved forward, for which purpose the block I is dropped, permitting thefinished barbs to pass. During this movement of the main wire lying inthe shaft up against the die in the head H, in which position it servesas a guide for the said main wires, and holds them in the requiredposition through the die to receive the barb-wires. When the movement offeeding the wires forward is completed, then the shaft begins torevolve, and then the incline on its end forces the core outward. Thismakes room between the end of the core and the die within the said shaftfor the main wires to turn in, else they would be bent or cut off. Thecore is held in this outward position during the revolution of the shaftby the said incline bearing against the cross-head.

Having described my invention, I claim-- 1. The die e, having the ovalopening placed one side of the center, as shown, and having the groovesff arranged in relation to the said oval opening so that one barb may bepassed between the two mainwires and the other barb pass out one side ofthe main wires, as described, and for the purpose specified.

2. The die g, having an elongated oval opening across its center, andthe grooves f f arranged close together across the center of the face ofthe die, so that both the barb-wires will be made to pass between themain wires, as described, and for the purpose specified.

3. The core a, in combination with the hollow shaft or shell B, androtating cutting an d coilin g headH, as and for the purpose specified.

4. In combination with the core a, and hollow shaft or shell B, the rodsb b, with their springs, and the inclines c on the end of the shell andon the cross-head the back and forth movement to the said core,substantially as described.
